Wikipedia Abstract

The chestnut-collared longspur (Calcarius ornatus) is a small ground-feeding bird from the family Calcariidae which also contains the longspurs. These birds have a short conical bill, a streaked back and a white tail with a dark tip. In breeding plumage, the male has black underparts, a chestnut nape, a yellow throat and a black crown. Other birds have light brown underparts, a dark crown, brown wings and may have some chestnut on the nape. In winter, they migrate in flocks to prairies and open fields in the southern United States and Mexico. The call is a two-syllabled chee dee.
